Foreign-born workers have accounted for more than half of the rise in
employment in Britain over the past year, according to official figures.

The number of foreign-born workers finding employment in the UK has risen by 225,000 to 4.26m over the past year, compared to an additional 192,000 UK-born men and women in work.

Figures from the Office for National Statistics also disclose for the first time that more than 112,000 people who were born in Bulgaria and Romania are already working in Britain, a rise of 14pc on the same period in 2012.

The rise comes amid growing concerns about a new wave of immigration from Bulgaria and Romania next year, when immigration restrictions are being lifted.

The new wave of immigration, which could lead to 50,000 people a year moving to this country from abroad, has led to warnings that Britain is facing an influx of people at an "unsustainable level".

Frank Field, a former Labour minister, a former Conservative minister, have warned that David Cameron must do more to tackle the "elephant in the room" and restrict European immigration.
